Heavy Land Rollers NZ - Water Ballast Rollers Built for New Zealand Conditions

Choosing the right size land roller depends on your ground conditions, stone size, tractor horsepower, and the width you want to cover each pass. At Plucks Engineering, we build heavy water ballast land rollers in a wide range of diameters, widths, and plate thicknesses so the roller matches your farm, not the other way around.

One of the most important factors is stone size. The larger the stones, the thicker the roller drum needs to be to prevent denting. As a general guide, our rollers are built in three common plate thickness options:

• 16mm plate - suitable for shingle up to fist size
• 20mm plate - suited to larger stones and heavier cultivation
• 25mm plate - recommended for very rough ground, large stones, or hard rolling conditions

Tractor horsepower must also be matched to the roller weight, especially with water ballast rollers. Larger diameter drums and wider rollers hold more water, which increases rolling weight and improves compaction, but also requires more pulling power. For example, wider heavy rollers used on flat land may require high horsepower tractors to operate safely and efficiently, while smaller rollers are better suited to hill country or lower horsepower tractors.

Ground shape also affects roller choice. On flat farms, wider rollers give faster coverage and fewer tractor hours. On rolling or uneven land, a narrower roller or twin roller setup can make towing safer and easier to control.

Because every farm is different, Plucks rollers can be built to any width, diameter, or plate thickness required. Our team helps match the roller to your tractor, soil type, and workload so you get the right weight and strength without overloading your gear.

Choosing the correct roller plate thickness is one of the most important decisions when buying a heavy land roller. The thickness of the drum determines how well the roller will handle stones, hard ground, and heavy rolling without denting or losing its shape. At Plucks Engineering, our water ballast land rollers are commonly built in 16mm, 20mm, and 25mm plate, with the right choice depending on your soil type, stone size, and how heavy you want the roller to run.

As a general guide, lighter ground with smaller shingle can usually be rolled with a 16mm drum, while paddocks with larger stones often require 20mm plate. For very rough conditions, large stones, or high-weight water ballast rollers, 25mm plate gives the extra strength needed to prevent damage and keep the roller running true for many years.

Heavier plate also increases the overall roller weight when filled with water, which improves compaction and helps push stones down instead of riding over them. However, the roller must still match the horsepower of your tractor, especially with larger diameter drums or wide rollers. Because of this, we help match plate thickness, drum size, and roller width to your tractor and ground conditions so you get the best result without overloading your gear.

All Plucks rollers are built using heavy plate and multi-run welding to New Zealand welding standards, and many of the rollers we built decades ago are still in use today. Choosing the correct plate thickness from the start is one of the reasons our rollers last for generations.

The best land roller setup depends on how much ground you need to cover, the size of your tractor, and how heavy you need the roller to run. Plucks Engineering manufactures single drum, double drum, and triple drum water ballast land rollers, along with twin roller towing systems, so the roller can be matched to the farm rather than forcing the farm to suit the roller.
Single drum rollers are often used where access is tight, such as vineyards, smaller paddocks, or farms with narrow gateways. These rollers can be built to almost any width with a narrow frame, while still using water ballast to give enough weight for proper rolling. They are also suitable for smaller tractors or lighter ground where a very heavy roller is not required.

Double drum rollers are the most common setup for general farm use. With two drums and water ballast, they provide good weight, good stability, and efficient coverage per pass. Rolling widths can start from around 2.4 metres and go much wider depending on the diameter and plate thickness chosen. This type of roller suits most farm work and can be built in different drum sizes to match the tractor horsepower available.

Triple drum rollers and wider setups are used where maximum coverage and heavy rolling are needed, especially on larger flat farms. These rollers carry more water ballast and more total weight, which helps push stones down and firm the ground properly. Because of the extra weight, they are normally matched to higher horsepower tractors and are often used where fewer passes are needed to finish the job.

For farmers wanting to cover more ground without buying a completely new roller, Plucks also builds twin roller towing frames that allow an existing roller to be mounted alongside another drum. This doubles the rolling width and can significantly reduce tractor hours during busy periods.

Because every farm is different, all Plucks rollers can be built to the required width, diameter, plate thickness, and towing setup, ensuring the roller works safely and efficiently with your tractor and ground conditions.
